Title: Heat treatment process for low-carbon steel
IPC: C21D1/18
Filed: 1971-04-30
Abstract: 1345387 Continuously heat treating steel bar BAU-STAHLGEWEBE GmbH 30 April 1971 [30 April 1970 13 March 1971] 12418/71 Headings C7A and C7N Non-alloyed or structural steel bar containing up to 0À26% C and up to 1À8% Mn and in a 10% to 70% cold-worked condition is continuously heat treated by passage through a rapid heating zone e.g. induction or electron beam, wherein the outer zone of the bar is heated to a temperature between 600 and 1300C so that the central region of the bar is heated at at least 100C/sec. to a temperature between 450C and Ac 3 , after which the bar is quenched before the central region undergoes any transformation and in the time interval between the temperature of the central region reaching 450C and that of the surface region falling to 550C. Preferably quenching is effected by water under pressure e.g. 6 to 30 litres per kg. of steel at 3 to 12 atmospheres, to produce an initial cooling rate of 1200 to 1500C/sec. and an average rate of at least 800C/sec. Quenching may be initiated when the outer and core regions are at the same temperature, and may be followed by a further treatment at 100 to 340C, particularly for 20 to 30 minutes. The process is applied particularly to bar for concrete reinforcement.

Title: Improvements in or relating to processes and devices for measuring the compactness of compressible bodies and especially of cigarettes
IPC: G01N33/02
Filed: 1966-03-22
Abstract: 1,142,812. Measuring compressibility; electro-physical measurement moisture. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. March 22, 1966 (March 26, 1965], No.12456/66. Headings G1N and G1S. A device for measuring the resistance to compression of compressible bodies particularly cigarettes comprises a tray 2 for housing the bodies under test, a balance whose beam 3 is capable of receiving the tray 2 at one end and at the other end two successive predetermined weights, means in the form of a plunger 5 for exerting a variable pressure on said body and means for measuring the deformation of the body beyond the initial position when the second weight has been applied. In a preferred form of the device the plunger is moved at right angles to the beam 3 and the travel of the plunger is the means for measuring the compression. A sliding weight 13 is used to balance the weight of the full tray 2. With the loaded tray in position the weight 14 is placed on the end of the beam and the beam released by the operating lever 34, Fig.34 (not shown). A motor (not shown) is then operated to rotate screw means 7 to move the plunger 5 downwards until the motor is stopped by contact 12 at the point of equilibrium. A graduated disc 9 connected to the plunger is set to zero in this position. The weight 15 is then placed on the beam and the motor started to move the plunger 5 downwards until the motor is again stopped at the point of equilibrium. The reading on the disc 9 is then a measure of the compression of the cigarettes. Pins 18 are provided which penetrate into either end of the cigarettes and are connected to two brass plates which are connected to the terminals of an ohmmeter. The measurement of the resistance gives a measure of the moisture content of the cigarettes.

A bi-colour ribbon control device for a startstop teleprinter of the kind having a print shaft 13, Fig. 1, driven intermittently through a onerevolution clutch mechanism (8), Fig. 2 (not shown), a driving member (10) of which is driven continuously by a driving shaft 27, Fig. 3, through a speed-reducing belt drive (26, 24, 23), and including a cyclically rotatable transmission shaft (88), receiving code bars 2, and a print control bar 38 for actuating the clutch (8), comprises a vibrator mechanism the throws of which are variable according to whether the teleprinter is receiving or transmitting, the mechanism being subject to a delay device adapted to synchronize the action thereof with a change from receiving to transmitting or vice versa. The ink ribbon 44, Fig. 1, is lifted by guides 45 mounted on a plate 43 pivoted at 48, through a cam 39 on the print shaft 13, the throw of the guides being controlled by an abutment 52 on a lever 53 which is pivotable between a position in which a projection 51 on the plate 43 engages the abutment 52 and a second position, as shown, in which the projection 51 misses the abutment 52 when the guides 45 are lifted. The position of the lever 53 is controlled by a bar 63 through a slide 58, the bar 63 being rockable by a slide 66 which is movable in response to rotation of the transmission shaft (88) by a bail 69 engaging the slide 66 through a pin and notch connection. Rotation of the transmission shaft (88) effects clockwise motion of the bail 69 through a cam (87), bell crank levers (83, 77) and a rod (74) after a delay during which a latch (97) and a pawl 104, Fig. 3, are removed from engagement with a sector bearing two sets 98, 103 of ratchet teeth, permitting the sector to rotate clockwise due to a spring 100 until an extended tooth 105 engages the latch (97). When transmission ceases, the transmission shaft (88) stops rotating, and the bail 69 is restored to its counterclockwise position step by step by engagement between a depending arm (102) of the bail and a pin (101) fixed to the sector, which is restored step by step by reciprocation of the pawl 104 by means of an eccentric 113 on the driving shaft 27 acting through an arm 112 and a lever 109.
